Answer» A cuboid is a 3D SHAPE. Cuboids have six faces, which form a convex polyhedron. Broadly, the faces of the cuboid can be any quadrilateral. More narrowly, rectangular cuboids are made from 6 rectangles, which are placed at right angles. A cuboid that USES all square faces is a cube. Properties of a Cuboid are:It has 12 edgesIt has 8 corners or verticesIt has 6 faces.The BASIC difference between a rectangle and a cuboid is that one is a 2D shape and the other is a 3D shape.The basic difference between a cube and cuboid is that a cube has equal length, height and breadth whereas in cuboids these THREE may or may not be the same. The cuboid can also be CALLED a right rectangular prism.Where l= length, b= breadth, h= height:Total Surface Area of Cuboid = 2(l*b+b*h+h*l)Volume of Cuboid = L*B*H |
